Fig. 1 describes a Motor Vehicle 1 for the sketch formula, wherein, has used apparatus of the present invention and the inventive method.Motor Vehicle 1 comprises an internal-combustion engine 2 and a speed change gear 3, simultaneously, settles a moment transmiting system such as clutch 4 to be used for the transmission of controlling and driving torque between Motor Vehicle and speed change gear.This speed change gear 3 is to link to each other with the transmission shaft 6 of Motor Vehicle 1 by a driven shaft 5.
The transferable torque of this moment transmiting system 4 can be when clutch separates fully null value and the maximum value when clutch is closed fully between regulate and determine.This just means that according to operating point, a torque can be adjusted in to the zone line of extreme value.Simultaneously, this moment transmiting system can be operated or regulate by a control gear such as reactor.This reactor for example can the electromechanical formula, motor-type, and hydraulic type, electromagnetic type or other form are operated, and simultaneously, can use control of a Stroke Control or power or power and regulate, in order that the corresponding transferable torque of control on corresponding operating point.
A control unit 7, which comprises at least power electronics unit and/or control electronic unit, and the transferable torque of this moment transmiting system is controlled or is regulated in requirement according to target, the situation of carrying of executing that according to target requires control in the present embodiment or regulate this clutch 4, therefore, controlled by the transferable torque of clutch.
This have combination computer unit control unit 7 and sensor and/or be in signal with other electronic unit as the control unit of a Motronic control maps unit and be connected.In addition, can form a signal to an anti--locking system (ABS) or an anti--adjusting (ASR) of skidding connects.Equally, can advantageously form the signal of controlling with a speed change gear and be connected.
The signal of sensor obtains by control unit.This control unit 7 has one or more data storages, wherein, at least can moment ground storage data and can being called again.
These signals can be processed as being filtered by the method or the algorithm of autocoding.
In addition, this control unit comprises a zone or parts, and it is by the running state of the input reality of input.The detection of this running state can realize that this program realizes by the fixed in hardware setting or by a software of setting up according to algorithm routine.
This control unit assessment input signal and implement a controlling method or a regulating method or start them according to the algorithm routine of autocoding is so that go the controlling torque delivery system according to a regulated procedure or a characteristic curve or a characteristic line family at any time.For this reason, the process of subordinate has in case of necessity: by the measurement of sensor to system's input parameter, the transmission of sensor signal, the average computation of data is according to the measured value detection of time, data computing, with data in the data storage storage and therefrom access, rating value calculates, the comparison of rating value and actual value, regulation rating value and control or adjusting rating value.
But the adjusting or the control of the adjusting of the jointing state of clutch or the control as the transmitting torque of a moment transmiting system are by stipulating that a rating value that is used for control gear realizes the jointing state of this control gear decision clutch.Control gear is for example stipulated a nominal position by control unit, simultaneously, when tuning or adjusting rating value, the position of a sensor monitoring reality.
Under a kind of control situation, according to the numerical value and the rating value of reality, based on the nominal position of reality one position and control gear, the stroke that pass through is just calculated and is correspondingly controlled this control gear.Under a kind of adjusting situation, just can harmonize by returning this numerical value in a position of clutch or control gear.
As meeting the method that purpose requires in addition, can realize a control with implicit parameter suitability.Simultaneously, characteristic line, the numerical value of characteristic line family or physical system are stored and make comparisons and adapt according to the situation of different running statees or time and reality.By this method, time dependent parameter is as the variation of the separation stroke that occurs by wearing and tearing or move and just can obtain consideration.
By a system that has or do not have the measured value reduction, just can realize the adjusting or the control of a system, simultaneously, this point can be achieved by the algorithm routine of software side or hardware side.
According to this, one of this control unit regulation is used for the rating value of control gear and for example by electric, hydraulic pressure, or the adjusting of motor type, make specified clutch position be controlled and this transferable torque is determined and is aligned.
This control unit has a miniature program stack, and its beat rate by an inside is controlled, and simultaneously, can realize the electronic clock of an inside.This survey data is promptly received according to the pattern and the method for beat with typical way, therefore, each measured value or each data value and the detected moment be can logic be connected and can be stored.
When the index that a time can be set corresponding to data value or a time point, this data value or this are measured parameter and just can be processed with the computing of mathematics and about the time, and this computing is precondition with the time sequencing.Therefore, for example also possible is, by the method for mathematics, for example uses the differential differentiate, obtains the derived function of data to the time.In addition, can also carry out a integration to measuring numerical value to the time.
This control unit can allow especially, according to position signal or position measurement numerical value, just can calculate this class signal of the speed that is used for a member and/or acceleration or measure numerical value.
Another organization plan regulation of the present invention, sensor so connects or settles, be acceleration or the stressed or speed that its () can directly be measured a member, need not must calculate rate signal of generation or acceleration signal according to position signal or stroke signal simultaneously.
This control unit 7 for example affacts on an element machinery or hydraulic pressure with its specified specified value as band sends on the reactor of clutch release slave cylinder, it receives on the cylinder 8 and by piece-rate system such as withdrawal fork acting on hydraulic pressure under the hydraulic element situation, and central separator machinery or hydraulic pressure is to guarantee according to target to require to control the torque by clutch transmits.
This reactor comprises that in the present embodiment a hydraulic pressure that has moving piston sends cylinder, and simultaneously, the position of piston in sending clutch release slave cylinder can and can be determined by an electromechanical formula operation equipment change.In the present embodiment, the operation equipment of described electromechanical comprises the motor and the crank gear of the worm gearing that connects behind the band, and it drives a crank-connecting rod.As being switched on or switched off or turning to conversion, this transmission cylinder position of piston just can be adjusted to different positions in possible range of operation or in the number range by the control motor.In order to determine this position that is aligned, when speed change gear when for example worm gearing has enough self braking action, disconnecting motor just can be enough.If when this self-locking action is not enough, can use a transmission device break or the locking mechanism that can connect and can disconnect.For system, what meet the purpose requirement especially is that this locking mechanism can be in whole operation area or only worked in the part area.
This sends the adjusting of the position of cylinder piston, and the route by hydraulic pressure is delivered to and receives on the cylinder piston and therefore the engagement positio of clutch is controlled.
Represent the reception cylinder position of piston of clutch position to be detected directly or indirectly.This point for example can so realize, is promptly receiving on the cylinder piston or is sending on the cylinder piston or on another piston of settling in the fluid stroke, settles a sensor or requires to connect a sensor according to effect.This directly (contactless or by linkage structure) can also replace by an indirect detection the detection that receives the cylinder piston position, simultaneously, another element or position of piston are also detected and just can calculate by the parameter of this data and hydraulic pressure route and to receive the cylinder position of piston.
By the signal that receives in control unit, the actual motion state of moment transmiting system just can predict and by meeting software or meet the algorithm routine of hardware, but tries to achieve a rating value of clutch state or transmitting torque.Corresponding with the rating value of clutch state a rating value that is used to control this control gear is set, this value can calculate and or also can from characterisitic family, obtain.This rating value just can be by regulating or controlling and harmonize as a motor by control example.This adjusting or control are as also can working as controlling or regulating according to this software that software is set up in control unit.In addition, this control can also realize as hardware.Control gear 7 be for example with air throttle sensor 9, the tachometer 11 that motor tachometer generator 10 and settle on transmission shaft 6 is connected.This control gear 7 can also additionally be processed other system's input value, and they for example provide by a data bus.
Present cited signal can be applied to the controlling torque delivery system as the signal of sensor signal or other electronic units.Described signal also has: the revolution that at least one is taken turns, engine torque, engine revolution, damper position, pedal position, motor vehicle speed, oil temperature, motor tractive moment, the jointing state of clutch, temperature in the clutch chamber, external temperature, air condition compressor moment, accessory temperature, the perdurabgility of the motor of closing, gear is put, switch intention signal, run signal, braking and hand braking signal, speedometer signal, the idle running signal, door sensor, starter release signal.
These signals can also for example be applied to engine control (Motronik) or an ABC-system or a transmission device control.
The operation of a shelves level in speed change gear 3 or selection are implemented by an operation equipment 12 as a conversion rod.This operation equipment 12 is to link to each other with controlling mechanism 14 on the speed change gear 3 by a connection set 13.This operation equipment sensor 15 is so installations or hinged or connection on operation equipment 12, and promptly it surveys a position or motion of this operation equipment 12.On controlling mechanism 14, settle a controlling device sensor 16, so that directly or indirectly detect the motion of this controlling mechanism 14.Sensor 15 and 16 information or signal are transported in the control gear 7 by signal connection device such as data lead or signal conductor.
This operation equipment 12 is to settle or operation by a conversion frame 17 as conversion rod, and its (12) links to each other with the controlling mechanism 14 of speed change gear 3 by a bindiny mechanism 13.This conversion frame 17 links to each other with Motor Vehicle respectively with speed change gear 3.Connection between controlling mechanism and operation equipment can realize with elasticity and/or a stroke gap mode, described controlling mechanism links to each other with the central exchanging shaft of interior gear change system (inneren schaltung), described operation equipment such as outer gear shift system (Au β enschaltung).This flexible application examples is that 14 central exchanging shaft and outer gear shift are that vibration between 12 is isolated as gear shift in can being implemented on request.Stroke gap in the bindiny mechanism 13 between structural group 12 and 14 for example can produce by wearing and tearing.
The bindiny mechanism of describing in Fig. 2 13 between the controlling mechanism 14 of operation equipment 12 and variable speed drive side can be by lever, pipe fitting, rod member or bolt bar are embodied as and are rigidly connected, simultaneously, this operation equipment is that moving of bidimensional is converted into bindiny mechanism's 13 same moving and it is delivered on the controlling mechanism along gear shift stroke and selection stroke substantially.
Another may scheme be to use bindiny mechanism and bindiny mechanism that is used for doing along the gear shift stroke transmission that 13, one of two bindiny mechanisms are used for transmitting along the selection stroke stroke.These bindiny mechanisms 13 for example realize by two flexible axles.
Because bindiny mechanism 13 can be provided with elasticity and/or stroke gap, so the motion of the relative operation equipment 12 of the motion of controlling mechanism 14 can in advance or fall behind, this means, the motion of controlling mechanism just follow the motion of operation equipment indirectly and can form a temporal hysteresis and space between the motion that these are connected move or two motions of these members 12 and 14 do not have coherence when taking place.
Apparatus of the present invention dispose a sensor at least and are used to detect gear shift stroke and/or selection stroke and comprise that the sensor of settling on the position of a system of gear shift outside 15 is used to detect the stroke that the one dimension at least of operation equipment 12 is fastened in gear shift outside.
At least one controlling mechanism sensor 16 can directly or indirectly be connected on the central exchanging shaft of the system of gear shift within the variable speed drive or the zone in.The connection of this controlling mechanism sensor 16 simultaneously is to realize with type in such a manner, for example the one dimensional motion of a transfer unit is transmitted or is transformed in the motion of the bidimensional of controlling mechanism, and the one dimensional motion of the motion of this transfer unit is by sensor.
In addition, the two-dimensional motion of controlling mechanism can be converted to the one dimensional motion of a movement means by a transfer unit.The sensor of the available again one dimension effect of this one dimensional motion.
This sensor provides a signal according to this, and it is formed by the component motion of controlling mechanism on gear shift stroke and selection stroke directions, therefore just produces the superposition of travel information to a signal.Connecting on the controlling mechanism under the situation of two sensors, can also realize so embodiment, be at least one sensor gear shift stroke and the one-component of selecting stroke, simultaneously, the mutual structure of the link position of these two sensors in an angle, according to this, the signal of sensor is incoordinate.For example, the connection of sensor is vertically disposed mutually.
At the sensor of using an one dimension job during as the controlling mechanism sensor, this signal or measured value are not position settings of single ground corresponding adjusting mechanism.At sort signal is under the situation of polysemy, and the signal of this operation equipment sensor can additionally be assessed, so that can determine the position of controlling mechanism singlely.
In addition, can also so settle by two sensors, promptly respectively have a sensor to select stroke and gear shift stroke.
The gear shift displacement configuration schematic diagram (Schaltschema) of bidimensional is transformed on the measured zone of sensor of an one dimension job, can describes as projection by favourable mode of execution.Therefore, two different positions in gear shift diagram can be designed as a numerical value in the sensor values scope as an example.Simultaneously, when carrying out gear identification, this numerical value can corresponding no longer singlely class position.
The controlling mechanism sensor signal is connected with the logic of operation equipment signal can eliminate this ambiguity.As an example, this controlling mechanism sensor so connects, and promptly a gear 2 in the gear shift diagram of a gear shift modified gear provides identical controlling mechanism sensor signal with a gear 3 after conversion.Because the zone after 2 class in gear shift row (schaltgasse) are arranged in, and 3 class are arranged in more preceding zone in another gear shift row, just can provide a signal by the operation equipment sensor, by it, the position of in front/back just can be differentiated out, and 2 class just can come with the difference of 3 class.
Fig. 2 b represents the gear shift diagram of the gear shift modified gear of a variable speed drive 3 concisely, wherein, has described single gear shift row 20, gear shift stroke 22 and selection stroke 21.This selection stroke is used for the selection between the gear shift row, and this gear shift stroke is used for the motion in the gear shift row.The gear shift diagram of a common gear change system that is used for transport motor car (schaltung) has only been described one of a plurality of possibility modification of motor vehicle gear changing figure.This operation equipment can cause a kind of selection between two class under embodiment's situation of Miao Shuing herein along the motion of assortment (Gasse) 20 on the gear shift stroke directions.Shown in gear shift diagram in, for example in first gear shift row, settled first and second class, in second gear shift row, settled third and fourth and in the 3rd gear shift row, settled the 5th and return shelves.This selection of waiting to regulate class can also realize by operation equipment is moved along the stroke 21 of selecting stroke.Described an example modification of apparatus of the present invention in Fig. 3 a and 3b, the two-dimensional motion that it makes controlling mechanism converts the one dimensional motion of a movement means to by a transfer unit and detects or supervision by the stroke sensor of an one dimension job.
Described the part of apparatus of the present invention in Fig. 3 a, simultaneously, this central authorities' shift shaft 30 is by the gear shift pull rod connection device 31 definite maximum angle skew that is shifted when gear shift rotates.This selection pull rod connection device 32 is but selecting vertically to be applied effect during the gear shift row, and therefore, a stroke motion takes place shift shaft.The cooperative action of the connection set by this selection pull bar and gear shift pull bar, this axle 30 just are placed in a rotation-translation-motion as rotate and/or stroke motion during selecting.The for example potentiometric connection control of sensor realizes by a curve disc or a cam member 33 in this example, against it, and the connection of transmission of the lever arm 34 formation power of a sensor or structure closure.The connection of lever 34 on curve disc 33 of sensor 35 can take place by a spring, therefore, guarantees lasting contact between lever 34 and curve disc 33.This spring can be placed in sensor housing inside.
Among the embodiment who describes in Fig. 3 a and 3b, the zone of action 34a of lever 34 has a connection area, just can monitor the position or the motion of controlling mechanism by its position or motion.If curve disc 33 is by around the rotation campaign of axle 32a the time, then corresponding mounting zone 33/34a also moves, and therefore, element 34 also moves.The stroke motion of member 32 just causes the stroke motion of a curve disc 33 and therefore causes the motion of a mounting zone 34a equally.
A motion of moving-rotating of controlling mechanism (30,32) causes rotatablely moving of a mechanism 34 in this enforcement, its (34) is connected with the input component of the one dimensional motion of a sensor.
The curve disc or the cam 33 that are used to control lever 34 described in Fig. 3 a and 3b shown in Fig. 3 b, also can be set to smooth surface.Ratio between the gradient of the corner of axle 30 maximums and curve disc or cam 33 is used for determining that the sigtnal interval is with the single signal numerical value corresponding to each gear.
At one is not plat surface 33 during as curved surface, just presents the interval (Abstand) between the corresponding gear of being in of a variation in the signal of controlling mechanism sensor.By determining the shape or the surface of curve disc or cam member 33, the signal structure of the signal of controlling mechanism sensor also has the sequence of the respective signal value of the corresponding spacing of corresponding gear signal value and corresponding gear to regulate.
In Fig. 4, described by the signal of operation equipment sensor and the position of this operation equipment 12.The position of a Motor Vehicle transforming gear bar 14 can be represented in the position of operation equipment 12, and the zoning of the position of transforming gear bar is consistent with the position of putting gear simultaneously.
The signal 100 of this operation equipment sensor has one from minimum signal U
0104 bandwidth to peak signal Umax105.At extremum U
0And Umax (104,105) signal of setting operation device sensor in the signal area between, as be connected sensor on the shelves levels conversion rod, described signal is being represented some positions, they are in the gear put of a speed change gear, when operation equipment moves, by this operation equipment, may occupied or inswept position as shelves level conversion rod.
This operation equipment sensor signal 100 has the characteristic of an one dimension in the present embodiment.The one dimension characteristic of this operation equipment sensor signal of describing in Fig. 4 is represented operation equipment moving along the gear shift stroke in the gear shift modified gear, do not consider simultaneously along the trip segment of selecting stroke, as when operation equipment moves, these gear shift row have changed.
The trip signal 100 cannot under any circumstance directly provide by selected gear shift row and differentiate result (AufscluB), because arrive the conversion of another gear shift row, cannot detect with signal 100 singlely.Can realize judgement about the gear shift rank transformation to signal 100 as the differentiates of the assessment of the function of time and/or possible 100 pairs of times of signal for one, this point control instrument can detect.
When a gear shift rank transformation, there is a motion stage of operation equipment, it is almost static along the gear shift stroke.By control unit evaluation operation device sensor signal the time, the conversion of such gear shift row just can be identified by the time-delay contrast of signal.
If but the controlling device position is that single value is known based on the data of the controlling mechanism sensor that detects and the data of operation equipment sensor, the class of being inserted just can be determined so.In addition, just can discern in advance under the corresponding situation along with time detecting at one, this speed change gear is to be controlled in which gear, even gearshift procedure does not also finish.
Be connected on the operation equipment and be used to detect under the situation of selecting stroke at a sensor, just can realize that by the operation equipment sensor signal gear of a single value is discerned.This connection for example can realize that this movable joint makes sensor be connected with operation equipment by a lever by a movable joint.
Have the control program of autocoding or the control gear of regulating method and can have a program (method) step, this step just can be determined the respective synchronization position of single valuedness gear and borrow gear that these location recognition insert and the gear shift that correspondingly identifies actual selection to be listed as according to the motion of operation equipment and controlling mechanism and as the function of time.
This have one and understand the neutral position of operation equipment with the signal list of the position 101 corresponding to numerical value of operation equipment sensor signal 100.The gear 2 that on behalf of these operation equipment sensor signals, the operation equipment sensor signal of concluding at 102 places inserted, 4 or return position under grade situation, simultaneously, the operation equipment sensor signal of concluding at 103 places is consistent with the position at the operation equipment of inserting gear 1,3 or 5 o'clock, and the gear shift modified gear that for example is based on Fig. 2 b this moment disposes.
Be in one with above-mentioned different gear shift modified gear situation under, then differently layout is also correspondingly done in the class position.With the corresponding class position of the signal of in signaling zone 102, concluding be, when inserting a gear, these gears require operation equipment to move on a certain direction, and simultaneously, the signal of concluding in signaling zone 103 but requires operation equipment to move upward the opposing party.
Signal 102a to 102c or 103a to 103c with respect to group 102 or the 103 operation equipment sensors of concluding just represent the position of operation equipment in the gear shift modified gear according to this respectively, these positions are observed from middle position, be with one downwards or the motion that makes progress in addition be precondition.The position of operation equipment in gear 1,3 or 5, shown under a gear stages of inserting, because the contingent diverse location that structural type and error condition caused of speed change gear is same, at gear 2,4 or also may be this situation when returning grade.These possible diverse locations can be detected and/or obtain and can be used for gear to discern with adaptive mode.This just means, the identification of the state by a synchronizing position just can detect one and be used for the exemplary value of gear and therefore, can realize the detection of the gear of inserting.
That the numerical value of this synchronizing position can change in the Motor Vehicle length of life or self change, simultaneously, these variations can be known and can be considered when gear is discerned.This adaptation adjustment can realize in different motion states.
Can put down in writing operation equipment moving by the detection that the operation equipment sensor is done along the gear shift stroke from a position to the another location to the operation equipment stroke.Difference between a kind of corresponding gear that comprises in group 102 or 103 can be realized by the different sync bits and/or the end position of operation equipment.In addition, the signal mating reaction with the controlling mechanism sensor also can realize a monotony layout.
Synchronizing position or assortment end position or end position can by one to corresponding signal analysis and detecting in time know.If people are actuating or this operation equipment of conversion and inswept synchronizing position or kayser (Rastier) position on a gear direction, stroke that so will an altered sensor signal of instantaneous appearance for the moment between a relation, because effect has additional force in the on top described position, it has changed one time one of stroke relation.These active forces are that the structure by speed change gear causes.
For example the change of the slope of a stroke-time-signal can be determined and differentiates as one of above-mentioned characteristics by control unit.As an example, a stroke-time-relation has been described in Figure 15.
Same gear shift intention can be by sensor signal detection, simultaneously, can realize that different being used to discern the method for gear shift intention.One may scheme be, the signal of sensor signal or at least one sensor is monitored and can be defined as over time by this signal the index signal of a motion intention.If for example this operation equipment is in static and sensor basically and detects an operation equipment position that has changed from a time point to, a shift pattern just may exist so.Equally, when threshold value for position or speed or acceleration be exceeded and this value not in the position of rest zone time then and may exist a gear shift to be intended to.
In this case, control unit is to the numerical value of sensor signal and numerical value that stores in storage compares and just can discern a gear shift when surpassing or be lower than the numerical value of this signal is intended to, this clutch just can so be controlled by control gear and controlling mechanism like this, be that it is opened, so that allow a gearshift procedure.
Advantageous in the identification of this gear shift intention is that resulting signal is so evaluated, promptly can not produce gear shift intention signal owing to the vibration in the Motor Vehicle makes the conversion vibration of bar.
When gear shift intention signal was recorded in control unit, this clutch degree like this that is unlocked that is to say that this controlling mechanism is so controlled with a rating value, transmission of torque does not promptly take place and can implement a gear change.
According to the derived function of the obtainable operation equipment stroke of the stroke-time-signal of operation equipment sensor to the time, and, just can realize one to the identification of the motion consciously of operation equipment or the identification of a gear shift intention according to the speed or the acceleration of operation equipment.One of identification of this gear shift intention or operation equipment are had a mind to the identification of motion and can be compared with reference value or compare with reference value and determine by the time dependent speed of operation equipment or acceleration by the time dependent position of operation equipment.Simultaneously, this reference value can be fit to that mode is determined and/or be assessed.
Gear identification can also be with a signal and operation equipment stroke, and the dependence of operation equipment speed and/or operation equipment acceleration realizes, simultaneously, these signals can also based on a processing and/or filtration after and/or the signal of summary detect.
Particularly advantageously be, shifted to an earlier date, that is to say that gear up conversion that just is identified in service at gearshift procedure.Can know in time according to this, should make the clutch closure, so that in a definite gear, make skidding between the driving side of clutch and the slave end be adjusted best or prevent with which type of extruding force or which type of speed.Gear by this identification reality of doing sth. in advance just can be controlled an engaging process easily.By motion or the position of supervising controlling mechanism or operation equipment continuously, just can all note a change in location of this mechanism (device) any time.By a basic continuous detection, not only can detect end position, and can identify each neutral position at any time this device (mechanism) stroke.The work that the needed sensor of detection of this continuous or stable position to controlling mechanism and/or operation equipment is should be able to be in available stroke range continuous substantially.
The method that is used for discerning a gear shift intention in the present invention, this controlling method can be by the operation equipment sensor signal over time or by to the time derived function of its differential and tell, the change in location that whether has the operation equipment of a hope, that is whether have gear shift intention or whether have the change in location of a non-operation equipment of having a mind to, for example may be the situation that the vibration transfer of Motor Vehicle is gone to the operation equipment.
In addition, possible is to tell by the natural vibration of operation equipment, and whether operation equipment has an altered vibration characteristics, as by manually may causing.
In Fig. 5, the signal 110,220th of controlling mechanism sensor has been described gear shift modified gear 200 as the function representation of stroke with sketch.The gear shift modified gear 200 of a Motor Vehicle is for example to describe as a notch track (Kulisse) of bringing retrace 5-shelves speed change gear back to, and simultaneously, gear 1 to 5 describes and return the position of shelves by position 206 expressions by position 201 to 205.Stroke in gear shift diagram or position then project on the sensor signal S of an one dimension according to arrow.
The signal of this controlling mechanism sensor 220 comprises the zone from minimum signal Uso215 to maximum signal Usmax214.The position 201 to 206 that is used for describing the terminal of gear shift modified gear (schaltkulisse) gear shift row is to represent by the signal numerical value 208 to 213 of controlling mechanism sensor signal.
If this controlling mechanism is positioned at the position 201 of expression first gear, the controlling mechanism sensor signal just has numerical value 208 so.If controlling mechanism 201 is transformed into position 202 from the position, that is second gear, then the signal of controlling mechanism sensor changes to signal value 209 from signal value 208.Correspondingly also be applicable to controlling mechanism 203 changes of 204 to the position from the position, simultaneously, the signal of this adjustment joint mechanism sensor changes to 211 from numerical value 210.If the state of controlling mechanism 205 changes to position 206 from the position, the signal of controlling mechanism sensor changes to numerical value 213 from numerical value 212 so.The motion of controlling mechanism in the gear shift of gear shift modified gear row then causes the signal of controlling mechanism sensor to change to from one of acceptable operating point 208 to 213 on the adjacent acceptable operating point 208 to 213 a bit.
Be listed as from a gear shift the conversion of another gear shift row at controlling mechanism, the signal numerical value 221 and/or 222 in the signal area of controlling mechanism sensor just is reached and is exceeded.This controlled program of identification that one of two numerical value 221 and/or 222 are reached or are exceeded indicates as the change that a gear shift is listed as.
201 quilts are brought to position 203 if controlling mechanism is for example from the position, and so, the numerical value of controlling mechanism sensor signal changes to numerical value 210 from being worth 208.From being worth 208 under the change situation of value 210, in transient time, just arrive numerical value 209 this.Because numerical value 209 is represented controlling mechanism position 202, this control unit or control program are just told, this numerical value 209 is not harmonized for a long time, but moment reaches and surpasses.Whether be exceeded in order to estimate a signal numerical value that changes as a kind of gear shift row of indication, can use the signal of operation equipment sensor equally.Under the situation of inswept for example position signal 209, the signal 100 of this operation equipment sensor is located in the zone of numerical value 101 when gear shift row change.Just representative of this signal numerical value 101, this operation equipment mediate or neutral or in the zone of selecting stroke.According to this, one makes the combination of the information of signal 100 and 220,320 just can realize a monistic discriminating about inserting gear or controlling mechanism physical location.
Just identify surpassing 221,222 o'clock control units of numerical value or control program, the gear shift row have been transformed and stable arrival numerical value 210,212 o'clock, this control program determined that the position 203,205 of controlling mechanism has reached.A combination that makes signal 100 and 220,320 can also realize the judgement of a monodrome in the case.
Gear shift modified gear 300 and a controlling mechanism signal 320 have been described in Fig. 6.Compare with Fig. 5 now with respect to the layout of controlling mechanism sensor signal 320 and realize with other type and mode in the position 301 to 306 of controlling mechanism in the gear shift modified gear.Signal numerical value 308 to 313 is done in the zone of controlling mechanism sensor signal 320 with respect to limiting value 314 and 315 and with respect to configuration so selection in this variant embodiment of the position 301 to 306 of controlling mechanism in modified gear, be that these signal numerical value are positions of coming from gear shift row, rather than direct neighbor.For example, from the position 301 when carrying out the transition to position 302, signal must change to numerical value 311 from numerical value 308, and simultaneously, signal numerical value 309 and 310 must be exceeded, and these numerical value are corresponding with position 303 and 305.Can single valuedness realize again for being identified in the stable status of inserting gear.Under current intelligence, this control program must be assessed the dynamic characteristic of this controlling mechanism sensor signal, in order that determine, whether the numerical value of a controlling mechanism signal be moment ground be received or passed through or whether a signal numerical value is harmonized chronically.In order to discern the monotony position of gear, same, signal that can application operating device sensor.
The signal numerical value of describing at Fig. 5 and 6 208 to 213 or 308 to 313 equidistant be corresponding at interval with the specially for carrying out form of applied control gear as transfer unit, these control gear for example are curve disc or cam member or pull bar, simultaneously, curve disc for example can be set to bidimensional or three-dimensional curve disc and for example produce the signal numerical value configuration of a non-equidistance, and these numerical value are put consistent with special gear.The configuration of sort signal numerical value is depended on use which type of control gear.Equally also suitable form of implementation can be set, they both can arrange equally spaced signal numerical value adaptive with corresponding gear, perhaps arranged non-isometric signal numerical value adaptive with corresponding gear.
The bidimensional system of this gear shift modified gear 200,300 can be switched to the controlling mechanism sensor signal 220,320 of one dimension by apparatus of the present invention.This controlling mechanism signal is loaded with about the information of the position of controlling mechanism in the gear shift row and about be listed as the information that another gear shift row change from a gear shift.At controlling mechanism is that the signal of this controlling mechanism stroke sensor is a single value under position (201 to 206,301 to the 306) situation of a possible state of rest.Under the position change situation of controlling mechanism in the gear shift modified gear, just may cause gear of " inswept " or " crossing " in the adjustment neutral position or the time by the neutral position, that is to say, a kind of surpass one and the corresponding signal numerical value of gear take place.
Detection to the operation equipment position can controlled program be used for by the operation equipment sensor, and the controlling mechanism sensor signal of non-single value when surpassing the neutral position is made correct assessment.
The dynamic characteristic of operation equipment and/or controlling mechanism can be detected and be applied to differentiating, and whether the numerical value of a controlling mechanism sensor signal has reached and be aligned or be exceeded, in order that realize another numerical value of controlling mechanism sensor signal.This control can be discerned by the dynamic characteristic of operation equipment signal and/or controlling mechanism signal, whether by controlling mechanism be placed into a definite gear and according to this definite controlling mechanism signal numerical value on a basic time lag, whether keep constant or almost keep constant or whether this controlling mechanism be to be reached moment and to be exceeded by actuating or mediate zone or a controlling mechanism signal numerical value, and this signal numerical value is consistent with the position of the gear of inserting.
To have good control characteristic when separating engaging for an automatic clutch system, the position of operation equipment and controlling mechanism and/or the information of speed and/or acceleration can be applied in the control performance.Malfunctioning at two sensors such as the generation of one of controlling mechanism sensor or operation equipment sensor, in defective or the failure condition, always impregnable sensor can guarantee promptly to start characteristic.
This characteristic of promptly starting for example so guarantees promptly have under the failure condition at the operation equipment sensor, and the location recognition of controlling mechanism is that the signal by the controlling mechanism sensor guarantees; And the dynamic property of the dynamic property of operation equipment by controlling mechanism just can be enough to obtain detect and/or it is adaptive to obtain, so that guarantee at least one limited operation of system.
Between the operation equipment 12 of Motor Vehicle and controlling mechanism 14, have under the situation of connection set 13 substantially rigid, non-damping; the assessment and/or the suitability of the dynamic property of controlling mechanism can be applied to, promptly start the identification of guaranteeing the gear shift intention in the characteristic range by the controlling mechanism sensor.
Have malfunctioningly at the controlling mechanism sensor, when defective or fault, can in the scope of promptly starting characteristic, implement a gear identification by the assessment or the suitability of the signal of operation equipment sensor and operation equipment signal.This gear identification is so to realize, for example determines this synchronizing position by the operation equipment sensor.This point is possible by the operation equipment sensor to a great extent, need only the synchronizing position of these single gears this moment, that is the synchronizing position that is summarized in gear in the group 102 and 103 is incoordinate, therefore, just can reach adaptive based on the power performance of the stroke-time-characteristic of operation equipment signal and and then can discern.
In addition, can detect the gear that this is inserted, as long as clutch began closure or was closed this moment by the revolution characteristic of the relative output revolutions of input revolution of for example speed change gear.Can detect a shelves level position by this control unit according to the reference value that stores in given engaging under the stroke situation with the comparison of actual value.
These transfer units of describing in accompanying drawing in front are as the transfer unit work of curve disc or cam member by one, they can be the two-dimensional signal mode, or the structure of three dimensional signal mode, also can be by a device job on curve disc by putting, therefore, the motion of curve disc bidimensional just is convertible on curve disc by the motion of an one dimensional motion of the device put and this device detected by a sensor.
The embodiment who describes in the accompanying drawing realizes a transformation of narrating above by the lever that a movable joint connects afterwards.The sensor of Shi Yonging for example is a sensor with rotating input shaft like this, and simultaneously, the direction of operating that works is the setting of one dimension.Such sensor only allows the motion of an one dimension, therefore, one to the sensor arm the spring energized effect on a direction of operating can to make the motion of the motion of this sensor arm and controlling mechanism be the single valuedness configuration.

In addition, can realize the arrangement of a flexibility by the connection of flexible axle in the casing 810 of Motor Vehicle, this is obviously favourable when considering narrow structure space condition.
Figure 14 shows a block schematic that is used to control a moment transmiting system 1000, and simultaneously, a controlling mechanism 1001 is used to bear or control the adjusting of this torque that can transmit.This moment transmiting system 1000 is operation automatically as clutch, this means, a control unit 1002 can be distinguished by the signal of input, the clutch closure or openness, or which kind of is favourable in the part closure.This clutch is placed in one and does not show motor and do not show between the transmission device that simultaneously, the selection of the gear of this variable speed drive, that is the selection of manual transmission ratio are for example implemented by the driver in power stream transmits.To use an operation equipment such as conversion rod for selecting gear.In addition, on variable speed drive, settle a controlling mechanism, gear-changing component such as conversion rod in its conversion variable speed drive.This operation equipment and controlling mechanism are not described.
Directly or indirectly connect a sensor 1003 on controlling mechanism, it can detect position and/or the speed and/or the acceleration of controlling mechanism.Between controlling mechanism and sensor 1003, can connect a transfer unit that is used to make movement conversion.This sensor 1004 be connected on the operation equipment (directly or indirectly) and basically the detecting operation device along the position of gear shift stroke.In addition, can also detection speed or acceleration.
In addition, also on controlling mechanism or operation equipment, connect other sensor 1005.
The corresponding motion of these sensor be in signal with an electronic unit 1006 and be connected, this electronic unit is modulated the signal that is used for control unit.This electronic unit 1006 can be a mould one several (Analog-Digital) transducers or other unit.The signal 1007 of 1006 output terminal in the unit is complied with the motion that its Placement can be represented controlling mechanism or operation equipment, position, or other parameter amount.In a kind of connection, not only select stroke but also gear shift stroke all will influence the coordinate direction of sensor signal, the conversion of a sensor signal then is useful so, changes the signal that is produced later or only depends on the selection stroke at this, and is perhaps only relevant with the gear shift stroke.
This just means that these depend on selects the sensor signal of stroke and gear shift stroke to be reversed conversion, does not influence coordinate direction second or the 3rd simultaneously in order that obtain inner signal.This conversion just can realize by a typical Coordinate Conversion, and this Coordinate Conversion can be realized by the computing unit of control unit.
According to the present invention's design, at least one controlling mechanism sensor or two controlling mechanism sensors can so connect, and promptly along the stroke of two important coordinate directions, the sensor that detects by an one dimension mode detects.In addition, this operation equipment sensor detects the gear shift stroke substantially.The total information of these sensors can allow according to coordinate direction signal decomposition to be selection stroke and gear shift stroke.If on controlling mechanism, connect two sensors according to top method " obliquely ", that is to say, the sensor that each one dimension mode detects can be responded to moving along a projection of bidimensional stroke, a sensor also can be guaranteed one and promptly starts operation when second sensor fault so, because all information that need exist basically.
After Coordinate Conversion 1008 or do not have Coordinate Conversion in another embodiment, in control unit, have signal so, indicate to their single valuednesss controlling mechanism and the position of operation equipment in the gear shift modified gear.
For gear identification, parts 1009 are set in control unit at present, it is by realizing the coordination layout to the relative gear in real position with the signal of time correlation.
The identification of this gear can realize in such a manner, i.e. this gear shift modified gear signal field of enrolling a bidimensional.Simultaneously, according to gear these signals are carried out a distribution.This system be for example according to relatively or by bigger or less graph of a relation just can identifying, and which zone actual signal value is in and with this signal value and corresponding allocating of gear.
In a bigger relation or a less relation, constitute a signal and compare with threshold value.Can compare on the one hand, whether signal be less than or greater than one corresponding to separating the threshold value that gear shift is listed as.This relatively in, just can detect, this system is in which gear shift row, this means, has realized gear is limited on the gear that is arranged in these gear shift row.
Can check relatively with other signal whether a gear is in the front of gear shift row, in the zone of back or centre.Under the regional situation of having discerned an in front or back, just can determine or confirm the gear that this is actual with assortment information.
Can use the later signals of conversion 1008 for the identification of gear shift intention, simultaneously, in square frame 1009, carry out comparison again with a threshold (value).If a threshold value is not reached or is exceeded, then produce a gear shift intention signal and continue to be fed into function block 1010.With a threshold ratio than before, switched signal can also be by scaleization or conversion.Another of gear shift intention identification may mode be, carrying out a filtration treatment with threshold ratio before.This filtration can have a characteristic integration and/or differential, for example PT1-characteristic.A PT
1-filter show one in proportion-characteristic that postpones, that is to say that the relative end value of this signal is index variation.For example a jump function f (t) is (for time t, less than t
0, f=0 and for time t greater than t
0, f=1) be placed on the inlet of filter, then on filter outlet, produce a signal that takes up the beginning gradient, it adapts to a constant end value, and for time t, it is unlimited to lead to.In addition, before or after the filtration treatment of signal, a fixing or time dependent increment (Summanden) can be added on the signal mutually.
In addition, can also and consider that travel direction realizes the identification of gear shift intention according to the operation equipment speed or the acceleration that calculate or record.
The square frame 1010 of this control unit is the member of control unit, and it is responsible for the control of controlling mechanism.This square frame 1011 is function blocks, and it determines operating point by the signal 1012 of input, for example engine state parameters, revolution, torque and other parameters.In addition, the special parameter of other electronic units, for example the special parameter of ABS-electronic unit also can be considered.For example be the wheel revolution in addition.
This square frame 1010 produces the rating value of controlling mechanism, and it is correspondingly controlled, in order that make moment transmiting system realize a characteristic that exists according to the rule of autocoding.
The straight line of the band arrow of describing in Figure 14 has shown the signal connection, and they are arranged between the single member of system.It also is possible that the signal of not representing in Figure 14 in addition connects, and is for brevity because they do not indicate.
In the control of Figure 14 is single a storage element 1013 is set also, wherein, data are at least by time relation or moment or stored for a long time and can call taking-up again.In addition, data storage can so be organized setting, that is, it makes data store and/or data index storage in time with temporal sequence, so that clearly signal change is in time accessed by for example digitized program, as this point by differential be possible.
Figure 15 shows stroke signal curve 1100 over time, and signal is to detect on the controlling mechanism of a speed change gear by a sensor.The stroke of a controlling mechanism of expression on abscissa simultaneously, is described a gearshift procedure by the time of putting down in writing on y coordinate.
For example at 1101 gearshift procedures from the third gear to the fourth gear when importing a typical manual gear shifting gear shift constantly.In time zone 1106, the smooth of the curve of this moment indicates that the kayser effect (Rastierung) of third gear is overcome, and that is to say that under the situation of deceleration of motion, kayser power is overcome.
After the screens effect of third gear was overcome, speed was enhanced again, because the screens effect of zone line makes controlling mechanism quicken to enter the neutral position.In time zone 1102, people find out this controlling mechanism the speed of moment reduce or, a counter-rotating of stroke signal.
In time zone 1103, this gearshift procedure is implemented the synchronizing of fourth speed position, and wherein, the trip-time-characteristic has a less speed.In the further time changes and at 1104 places, this controlling mechanism is subjected to overvoltage by operation equipment in the fourth speed bit position, and then, at 1105 places, no longer stressed controlling mechanism is lax on the position of fourth speed.
This synchronizing position, but be identified according to Figure 15 single valuedness under the situation that gear is inserted, and simultaneously, a gear is distinguished, just can realize according to the situation of this synchronizing position.
Figure 16 represents a configuration structure 1200 that two sensors 1201 and 1202 are arranged, and they are placed in the regional interior of speed change gear and are connected with central shift shaft 1205 with 1204 by lever 1203.This sensor is by being threaded or plug is fastened on the substrate 1206, and simultaneously, sensor axis imports plate 1206 inside by an opening, and a sensor arm 1207 is placed in this plate below rotationally.This sensor arm links to each other with lever 1203 and 1204 by a spherojoint 1208 respectively.
Should can move on choice direction or gear shift direction by tie point 1210 by central authorities' shift shaft at present, simultaneously, this connection can for example realize by flexible axle and respectively connect a flexible axle being used for selecting motion and being used for the gear shift campaign.In the embodiment of Figure 16, this selection campaign is that of element 1211 edge axles 1205 moves, and the gear shift campaign is element 1211 rotatablely moving around axle 1205.
When the gear shift campaign, rotatablely moving of element 1211 is delivered on the lever arm 1203 by spherojoint 1213.The connection of lever arm 1204 realizes that by a movable joint and a lever 1214 it is a structure like this, and promptly when element 1211 rotated, lever 1214 did not move, and therefore, just said on the meaning that connects, and had the connection of a slip.Now, if element 1211 axle 1205 axially on when moving, then lever arm 1203 is by spherojoint 1213 same passive movements, simultaneously, lever 1204 is by transmission component 1214 passive movements, therefore, under the situation of selecting motion, sensor 1201 and 1202 just provides signal.
Stipulate that in another program of the present invention sensor 1201 so is connected with 1202, that is, sensor only detects the motion on gear shift direction, and other sensor only detects the motion in the choice direction.
Figure 17 represent a gear shift skeleton diagram as the process instance of identification of gear shift intention and/or gear identification and according to this with the control relation of a clutch.These square frame 1300 representatives are to the detection of motion of operation equipment and controlling mechanism, and this will further be connected to these sensors on the control unit to process these signals in addition by going up the sensor that connects at these devices (mechanism).Square frame 1301 processed sensor signals are the signal of operation equipment sensor for example, furtherly, whether a threshold value is not reached or is exceeded with regard to situation is differentiated in the position, that is to say, this operation equipment whether, driven limit outside the position of rest of a gear as conversion rod, therefore a gear shift intention is just found out.If exist a threshold value to be exceeded, or do not reach, then there is a gear shift intention, it is described in square frame 1302, and according to this, a gear shift intention signal is stand-by in the inner preparation of control unit.If there is no threshold value is exceeded or does not reach, and shows by arrow 1303 so, and the circulation of this gear shift intention identification just goes on always, exists up to a gear shift intention.
When having a gear shift intention in square frame 1302, by control unit, controlling mechanism is so controlled, that is, clutch is as separated described in the square frame 1304.In square frame 1305, whether this gear for example by the supervision of regulating mechanism position is detected and for example picks out at square frame 1306, arrives an end position.By to arriving the identification of end position, in square frame 1307, can determine, this gearshift procedure whether finished and in square frame 1308 this clutch be engaged by control again controlling mechanism.
According to square frame 1308 clutch can be realized according to the gear of having discerned, that is to say that engaging process is to carry out with a speed different according to gear.
Figure 18 represents the operation equipment 1400 of a band handle region 1401, and it is applied to selecting a gear in the speed change gear or places a gear.This operation equipment is to be placed in pivotally in the zone 1402, therefore, lever can be carried out one with the gear shift stroke with select motion that stroke adapts and be connected by articulated in zone 1403 and be connected with controlling mechanism on the unshowned variable speed drive by a link 1404.This supporting 1402 comprises a sphere or columniform regional 1405 substantially, and it is placed in movingly between the supporting fixture 1406 with by bindiny mechanism and is connected with Motor Vehicle 1407.A sensor 1408 can so be settled, be that it links to each other with holding clamp shell 1406 in zone 1409 and is connected with element 1405 sphere or columniform in zone 1410, therefore, a motion and therefore just takes place in sensor 1410 when operation equipment 1400 motion, and operation equipment just can be detected along moving of gear shift stroke.
Movable joint and the connection between sensor or the sensor axis at operation equipment can the identical pattern of structure realize, therefore, axle with imperfect circular cross section can be connected in the housing region that is similarly imperfect circle, like this, just can constitute the identical connection of a structure.
Figure 19 represents a gear shift seat 1500, and it comprises that one is used to operate the operation equipment 1501 of a speed change gear and the controlling mechanism that connects this speed change gear side by a bindiny mechanism 1502.This operation equipment 1501 has a pivoting support structure as conversion rod, and it is made of supporting shell 1503a and 1503b, also has sphere or cylindrical elements 1504, and it is placed between supporting shell 1503a and the 1503b.In addition, this operation equipment comprises a handle part 1505 and a pull bar 1506, and it forms a lever arm.
In following edge regions 1507, pull bar 1506 is movable the connection by a movable joint with connecting element 1502.It is that movable arrangement is connected to a fixed by fixed structure 1508 and Motor Vehicle with itself that this supporting shell 1503a and 1503b keep this operation equipment.
If on the operation piece 1505 of operation equipment, apply a steering force, then form an equilibrium of forces, simultaneously, steering force is in balance with the power that is connected of effect in bindiny mechanism 1502 by supporting force, and described supporting force acts in the zone of supporting shell.These power mark with arrow.
The configuration that Figure 20 basic representation is identical with Figure 19, having an exception is, between fixed element 1508 and supporting shell 1503a and 1503b, settled sensor 1510, they detect reaction force or supporting force 1511, as long as have a masterpiece to be used for this operation equipment in the manual piece zone of operation equipment this moment.Sensor 1510 is only made sketch in the present embodiment and is described, simultaneously, these sensors can be set to pressure transducer, force transducer or stroke sensor also can be based on electric capacity, resistance, the induction or the function of electromagnetic type and can be used as Hall-induction-sensor or piezoelectric transducer or stretching measuring transducer and work.
In addition, steering force can also detect by a detected connection power 1512.
Figure 21 shows the part figure of the spherojoint 1600 of an operation equipment 1601, and it only has been described as the center rod part, has also described supporting shell 1602a and 1602b simultaneously.This supporting shell is connected with holder 1605 with 1604 by flexible element 1603 again, wherein settles a sensor 1606, power such as the supporting force of its detection effect on elastic element in an elastic element.If on operation equipment, apply a steering force now, then in the zone of pivoting support, produce a reaction force, it is detected by sensor 1606.Whether this sensor can produce reaction to pulling force or pressure, that is moved forwards or backwards relevantly on gear shift direction with this operation equipment, is to point to forward or backward and decide with this steering force perhaps.
This sensor 1606 is to describe as the pressure transducer in Elastic medium in the present embodiment, simultaneously, as an example, this sensor can be set to capacitive transducer and a variation will occur at the electric capacity that elastic element is applied in the load condition lower sensor.Described conjunction cable 1607 in addition, simultaneously, as seen from the figure, this conjunction cable can fixedly mount, and they can be along with moving, because sensor is to be placed on the static member.According to this, the stress of cable connectors 1607 is reduced, so may just can reduce by the problem that snaps or fibrosis (Fibration) causes in this zone.
Figure 22 represents a sensor 1700, and it is consistent with the sensor 1606 of Figure 21, and is placed in the typical element 1701.This elastic element 1701 and elastic element 1702 are that the mode with direct force transmission stream or indirect force transmission stream is placed in the turned round connection between operating stem 1703 and the bindiny mechanism 1704 in this embodiment, simultaneously, this local figure part is connected 1507 consistent with the movable joint of Figure 19.In this zone, be applied with connection power 1512, it acts in the bindiny mechanism 1407,1502.This annular element 1705 surrounds element 1706, wherein having disposed spherojoint 1707 is connected under power 1512 situations with having executed at one, this central member 1706 just moves with respect to annular construction member 1705, and element 1701 and 1702 is stretched respectively and compresses, therefore, sensor 1700 just can detect this connection power or one and be connected the proportional power of power.Sensor 1700 among Figure 22 or the sensor 1606 among Figure 21 are set to the structure of pressure transducer or force transducer and place in bullet medium such as rubber or the elastomer.Simultaneously, this Elastic medium is being applied under the power load condition, a power is delivered on the sensor, and sensor just detects above-mentioned power.Member its performance classes with regard to distortion flexible or form of rubber is similar to fluid: that is to say, when the deformation resistance of active force that applies an outside and portion-form, normal stress or pressure just occur in inside, its sensor just can be involved or that be cast into such as pressure transducer detect.Further advantageously, this sensor is surrounded by rubber or Elastic medium, therefore, says to a certain extent to encase and prevent with being sealed external influence.Installing under such sensor situation, the member that range applications that needn't be common relatively is additional, because in this zone, use flexible element in principle, but their sensors configured not.
In addition, under a sensor situation that is cast into, the orientation of sensor can be arbitrarily basically, because pressure measurement is relative irrelevant with the orientation of sensor.
The plastic components of this regular application, it is used for separating or isolated vibration, can also substitute with the vibration isolated component of corresponding sensors configured.
The embodiment of the invention has additional advantage with a sensor configuration in the device of a controlling torque delivery system that has gear shift intention identification, the configuration of this sensor can keep simple relatively and be used for the conductors of information of sensor such as cable is in operation and can move or indeformable.Therefore, improved the operational reliability of whole system.
Be connected on the controlling mechanism of variable speed drive side with at least one sensor above-described sensor being connected on operation equipment such as the conversion rod, simultaneously, the signal of at least one controlling mechanism sensor can convert a gear shift stroke signal and a selection stroke signal to or have distribution like this, so according to preferred variant of the present invention, this controlling mechanism gear shift stroke signal can be discerned to be used for gear by controlled unit evaluation, and the controlled unit evaluation of operation equipment signal on the gear shift stroke directions is used for the identification of gear shift intention.According to this, two sensors (operation equipment sensor and controlling mechanism sensor) can provide a signal, and it represents a device (mechanism) moving along the gear shift stroke.
A sensor sensor signal is out of order or the situation of defective under, then corresponding another sensor or another sensor signal can be used for substituting.This means that the operation equipment signal can be applicable to gear identification or the controlling mechanism signal can be applicable to the identification of gear shift intention, this moment, corresponding sensor in addition was out of order.
Figure 23 a shows a gear shift modified gear 2001, and it is described on the coordinate system of a measured value 2002, simultaneously, and the voltage V of record sensor 1 on the X-axis of coordinate system
Sensor 1Voltage U with record sensor 2 on the Y-axis
Sensor 2Or signal U
Sensor 2This sensor 1 and sensor 2 for example are two sensors, they be placed on the controlling mechanism of transmission device side and the controlling mechanism that detects this transmission device side along the gear shift stroke or select moving or the position of stroke.This sensor 1 and sensor 2 for example are two sensors so, they be placed on the controlling mechanism of transmission device side and the controlling mechanism that detects this transmission device side along the gear shift stroke or select moving or the position of stroke.This sensor 1 detects selects stroke and sensor 2 to detect the gear shift stroke.The numeral 1 to 5 and capital R indicate first grade to the 5th grade and return shelves gear.Threshold value when the signal value G1 of the sensor signal of this sensor 1 is transformed into the second gear shift row 2004 with G2 with the first gear shift row 2003 is corresponding, or table is corresponding with the threshold value when a gear shift level 2004 is transformed into gear shift level 2005.The sensor signal U of this second sensor such as gear shift stroke sensor
Sensor 2Numerical value E1 and E2 representing inserting the threshold value that a gear is characterized when surpassing or not reaching.
Figure 23 b shows the signal U of this gear shift intention sensor
Sensor S, simultaneously detected on the neutral position 2010 of zone line basically.The value 2011 on, this gear 1,3 or 5 be placed into and with gear 2,4 or return shelves value 2012 corresponding.From one grade during to 2 grades of motions, this sensor signal is from being worth 2011 by being worth 2010 values of changing to 2012 at operation equipment such as conversion rod.
Figure 24 shows a block flow diagram, and its one of explanation is used for the program of gear identification, simultaneously, threshold value G1, G2 and E1 and E2 obtain from Figure 23 a.
This block flow diagram 2100 starts from flow process origin or beginning 2101 and 2102 questions in the enquiry desk, this sensor signal U
Sensor 1Whether less than a threshold value G1.If this is the case, then at the question of 2103 places, the sensor signal U of this second sensor
Sensor 2Whether greater than a threshold value E1.If be this situation equally, then the gear of being inserted is confirmed to be first retaining and at 2104 places, and stops this flow process at 2105 places.If the question 2103 obtains answering with " no ", then at the question of 2106 places, this sensor signal U
Sensor 2Whether less than value E2.If this is the case, then confirm as the 2nd grade at the shelves at 2107 places, flow process finishes then.If not this situation, then confirm as middle bay at the actual shelves at 2108 places.If the question 2102 is a negative effect, that is to say, answer and be " no ", carry out further question, the signal U of this sensor 1 so at 2110 places
Sensor 1Whether less than threshold value G2.If this is the case, then at the question of 2111 places, this sensor signal U
Sensor 2If whether be "Yes", then confirm as third gear and follow process ends at 2112 places greater than threshold value E1 and answer.If the question at 2111 places is answered for negative, then also to ask a question U again at 2113 places
Sensor 2Whether less than E2.If such situation, if then confirm as the 4th grade and then termination process or the question at 2113 places obtain the answer of " no ", bay and follow process ends in 2115 places confirm as then at 2114 places.If the question 2110 is negative result, in other words, it makes answer with " no ", asks a question the signal U of this sensor 2 so at 2116 places
Sensor 2Whether greater than E1.If this is the case, then confirm the 5th grade and then finish this flow process at 2117 places.If the question 2116 is a negative effect, then at 2118 question, whether this sensor signal U
Sensor 2Less than E2.If this question is just answered, then confirm as and return shelves at 2119 places.Situation in addition, then bay and then stop this flow process in 2120 places confirm as.
This program is based on the threshold value (curve) of Figure 23 a, and wherein, this threshold value E1 is applicable to all gears 1,3 and 5, and threshold value E2 is applicable to all gears 2,4 and returns shelves.People simply type and mode change native system, and wherein, threshold value is different for corresponding gear, as determining them by an adaptive job.
Figure 25 shows the flow chart of gear shift intention identification, and it originates in a gear identification and has taken place and discern gear or gear is identified.This flow chart 2500 shows a gear shift intention recognition process of carrying out with the PT1-filtrating equipment, and is such as described above.Along with the startup of program 2501, in the inquiry of 2502 places, whether actual gear of inserting is 1,3 or 5 grade.If this question obtains positive answer at 2502 places, then by the sensor signal U of the sensor that on conversion rod, connects
Sensor STime Calculation successively goes out the speed UVS of conversion rod motion.The calculating of this speed is to realize with the form that differs from ratio, wherein, and the sensor signal U that on two time points successively, detects
Sensor SDeduct mutually and removed by the time difference of two time points.This is the simple scenario of a computational speed, simultaneously, can also use other digital method or difference ratio method.Particularly can also ask difference to process to the signal value on two or three or four time point successively.
Therefore the speed calculation at 2503 places provides signal U
VS, it has been filtered by the PT-filter at 2504 places.This PT
1-filter shows a characteristic that postpones in proportion, and it was described once in addition in the above.Simultaneously, the answer of a hop function is a signal that rises with variable slope not, and it relies on a terminal value.Now in 2505 inquiry, ask a question, this filtration by filter by the signal U that sends
SWhether less than a threshold value.If this question is answered with "Yes", then there is a gear shift intention at 2506 places, then, EOP end of program.If the question at 2505 places is the answer of bearing, then can determine at 2507 places, there is not the gear shift intention.
Using under the velocity transducer situation U
VSNeedn't calculate.
If the question at 2502 places is the answer of bearing, then carry out question at 2508 places, in other words, so that determine whether this actual gear is a gear 2,4 or R.If this is the case, then, simultaneously, can use poor ratio method again according in the calculating at 2503 places and calculate the speed of conversion rod at 2509 places.Then, according to the filtrating equipment in 2504 and at 2510 place's rate of filtration signals with as signal U
fSend.Then at 2511 questions, this signal U
SWhether be, simultaneously, under the positive situation of replying, then identified to exist a gear shift to be intended at 2512 places greater than threshold value.If question is answers of bearing at 2511 places, then can determine at 2513 places, there is not the gear shift intention.If the question 2508 is the answer of bearing, that is to say with " no " and answer that then can determine at 2514 places, middle bay is placed into and does not exist gear shift to be intended to signal.The data of determine filtering and the comparison value of threshold value at 2505 and 2511 places can take place once comparison value less than threshold value and comparison value once greater than threshold value, this be because this to be in the gear of inserting be 1., or 4. or 5. under the situation, conversion rod is passive movement on a definite direction, in other words, at for example passive movement and corresponding with its direction according to this speed is determined and handle affairs 2511 and to be inquired earlier on the direction of gear 2, whether gear 2,4 or R be placed into and correspondingly this speed have an other direction or other indicating.Whether people can be positive or negative finding by question speed for example like this, whether conversion rod a significant motion has taken place, because for example inserted under second gear stages at one, it is nonsensical that conversion rod is operated on a direction, and this direction is not to be positioned on the direction of zone line.
In 2514 places exist, under bay or the zone line situation, can identify a gear shift and be intended to not exist, because according to control strategy, the clutch of being controlled is opened under the middle gear stages having inserted.Therefore, unessential is when this state, and whether gear shift intention is identified, because at the clutch of opening and insert under the gear stages, this is very possible thing.If for example when middle gear, there is the clutch of a closure, so in this case, the gearshift intention will detect, simultaneously, just can realize it according to the program in this square formula gearshift map, wherein, the calculating of speed and filtration work can be carried out simultaneously, and, gear shift intention signal can with the U that surpasses when existing
fIdentify the orientation independent of numerical value.
